MACHINE FOR RESTORING INSULATED WIRE.

SPECIFICATION forming part of Letters Patent No. 601,694, dated April 5, 1898.

Application filed August 20, 1897. Serial No. 648,929. (No model.)

act description.

1 The invention relates to insulated wire used for electrical purposes; and its object is to provide a new and improved machine for restoring'injured insulated wire by straightening the old wire, removing the insulation therefrom, and reinsulating the wire to permit its reuse the same as new wire.

The machine consistsprincipally of a winding device for winding up the straightened and newly-insulated wire and imparting a traveling motion to the wire under treatment, a straightening device for straightening the old insulated wire, a stripping device for removing the insulation from the wire,and a covering or winding device for winding the insu- .lating fabric upon the stripped and straightened wire.

The invention further consists of various parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure l is a side elevation of the machine, with parts in section; and Fig. 2 is a plan view ofthesame.

The improved machine is mounted on a suitably-constructed frame A, on one end of which is journaled a drum B, containing the old Wire 0 to be restored into newly-insulated wire 0, adapted to wind up on a drum D, journaled on the other end of the frame A. On the shaft of the drum D are secured fast and loose pulleys E, connected with other machinery for imparting a rotary motion to the said drum to wind up the new wire and to impart a traveling motion to the wire under treatment to cause the same to unwind from the drum B. The wire 0, after leaving the drum B, is passed one or more times around a drum F, secured on a shaft F, journaled in suitable bearings on the main frame A, the said shaft being connected by beveled gear-wheels F and G with a longitudinallyextending shaft G, rotated by the said gearwheels from the shaft F, receiving its rotary motion by the traveling Wire passing around the drum F. The shaft G serves to drive a spool-carrierH for winding the insulating fabric upon the Wire, as hereinafter more fully described.

After the wire 0 leaves the drum F it passes between vertically-disposed straightening-rolls I I I and I 1 of which the rolls I I 1 are journaled on a stationary frame J, while the other rolls I I are journaled on a frame J, laterally adjustable by means of a screw J 2 and nuts J By this arrangement the wire passing between the sets of rolls is straightened, and the adjustment of the rolls I 1 causes the wire to pass the rolls at such an angle that any short turns in the wire will be removed.

The straightened Wire 0 after it leaves the straightening-rolls passes between strippingknives K K for removing the old insulation from the wire. The knives K K extend vertically and have their cutting edges curved, as plainly indicated in Fig. l, to readily strip the old insulation off the wire as the latter passes between the two knives. The knives K K are attached tobase-plates K K held laterally adjustable on arms L L, respectively, by means of bolts K, screwing in the said arms and engaging lateral slots in the said base-plates. (See Fig. 2.)

The arms L L are supported on studs L L secured on brackets N N, attached to the main frame A, the studs permitting of turnings P, attached to the main frame A. The

On the forward end of the arbor O is secured the spool-carrier'H, carrying a spool H, from which unwinds an insulating material passing around'a' finger H likewise held on the said carrier I-I. The material 0 then passes to the wire after the same has left the -forwardend of the arbor 0 and'as the carrier H is revolved the material C is'wrapped upon the wire 0 in front of the rollers Q Q,

engaging the material on opposite sides, as will be readily understood by reference to the drawings. The newly-covered wire 0 unwinds from the rollers Q Q upon thedrum D to be wound up.

Now by the'arrangement described the speed of the wire asit is wound up on the drum 'D regulates the speed of the winding or cov ering device for placing the insulating material on the wire, so that the same numberof turns of the insulating material is given to each foot of wire, thus insuring a uniform covering of the wire. 7 V

. The machine is very simple and durable in construction and enables electric companies to restore their old injuredins'ulated wire in the manner above described. 4

Having thus fully described in y invention,

I claim as new and desire to secure by Letters Patent- 1. A machine for restoring insulated wire, provided with a straightening device for straightening the old insulated wire, and a stripping device in advance of the. said straightening device for removing the insulation from the wire, substantially as shown device for winding up the finished wire, substantially as shown and described.

3. A machine for restoring insulated wire, comprising a straightening device for straightening the injured insulated wire, a stripping 1 device forward of the said straightening device, for' removing the old insulation. from the straightened wire, and a covering or wrapping device in advance of the said stripping device, for placing a new insulatln g materlal on the straightened and stripped wire, substantially as. shown and'described. i V

4. A machine for restoring insulated wire,

comprising sets of rolls between which the" injured insulated wire passes'to straightenv V the same, a pair of knives between whiclrthe straightened wire passes, to remove the old insulation therefrom, an arbor through which travels the stripped, straightened wire, and a'spool-carrier on the said revoluble arbor,

for winding a new insulating material upon the said wire, substantially'as shown and described. 7

5'. A machine for restoring insulated wire,

comprising sets of rolls between which the injured insulated wire passes to straighten the same, a pair of knives between which the V Z straightened wire passes, to remove the old insulation therefrom, an arbor through which travels the stripped, straightened wire,a spool-' 1 carrier on the said revoluble arbor, for winding a new insulating material upon the said wire, means for imparting a traveling motion to'the wire,to passthe same through the said rolls, the knives and the arbor, and a drum driven from the said traveling wire, and connected with the said carrier, to rotate the same, substantially as shown and described.

6. A machine for restoring insulated wire, provided with a pair of knives having curved cutting edges between which passes the wire, the knives being laterally adjustable, substantially as shown and described.

7. A machine for restoring insulated wire,

provided with a pair of knives having curved cutting edges between which passes the wire,

the knives being laterally adjustable, and means for setting the knives ata desired angle at their cutting edges relatively to the wire passing between the knives, substantially as shown and described.
